Abstract

The invention discloses a detecting tool which comprises constant temperature equipment, a refrigerant heat dissipater, a heating module, a flowmeter, a first temperature sensor and a first temperature sensor assembly, wherein the constant temperature equipment is provided with an inlet and an outlet, and is constructed to enable the temperature of cooling liquid flowing out of the outlet to be constant, the refrigerant heat dissipater comprises a heat dissipating pipe and a heat dissipating body, one end of the heat dissipating pipe is connected with the inlet through a first pipeline, the other end of the heat dissipating pipe is connected with the outlet through a second pipeline, the heating module comprises a heating body used for generating heat, the heating body is arranged on the heat dissipating body, the flowmeter is arranged between the constant temperature equipment and the refrigerant heat dissipater and used for detecting flow of the cooling liquid flowing out of the outlet, the first temperature sensor is arranged on the first pipeline and used for detecting the temperature Ta of the cooling liquid in the first pipeline, the first temperature sensor assembly is arranged on the second pipeline or the heat dissipating pipe and used for detecting the temperature Tf of the cooling liquid after heat exchange, and thermal resistance theta of the refrigerant heat dissipater is equal to (Tf-Ta) / P, wherein P represents power of the heating body. The detecting tool can detect the thermal resistance of the heat dissipater.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a detection tool. Background technique [0002] In the frequency conversion air conditioning system, the heating value of the frequency conversion module is quite high, and the cost is relatively high. If the quality of the cooling system is unreliable, it is easy to cause the inverter module to burn out. In the related art, a refrigerant radiator is used to cool the frequency conversion module, but since the detection method for testing the thermal resistance of the refrigerant radiator is unreliable, there is a great hidden danger in directly using it on air-conditioning products. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, the present invention proposes a detection tool, which can effectively and simply detect the thermal resistance of the refrigera...
